What did researchers hypothesize regarding the infected female monarch butterflies?

• The infected mothers would lay more eggs on the anti-parasitic plant

• The uninfected mothers would lay more eggs on the anti-parasitic plant

• The infected mothers would not have a preference between anti-parasitic plants and regular plants

What was the independent variable in the monarch butterfly experiment?

• whether the butterflies were infected or not

• whether the plants were anti-parasitic or not

• how many eggs the butterflies laid

• what kind of plant the butterflies laid their eggs on

What was the control in the monarch butterfly experiment?

• the uninfected butterfly

• the regular plant

• the infection

• the environment
